The challenges of global change
Chemistry for Tomorrow’s World            Chemical sciences and challenges

                                          The chemical sciences are tackling many of the challenges faced by the world’s
                                          inhabitants and their environments. Some of the ways are illustrated in this
                                          video produced by the European Petrochemical Association (EPCA).



“Global change is creating
enormous challenges relating to
energy, food and climate change. It
is both necessary and urgent that
action be taken.
The Royal Society of Chemistry
is committed to meeting these
challenges head on. The RSC has
identified where the chemical
sciences can provide technological
and sustainable solutions, and are
promoting action and awareness in
these areas.”
